Vermicomposting is a process that involves biological, chemical and physical transformations of solid organic materials such as agricultural residues of plant and animal through the use of microorganisms and earthworms. There are three main classes of earthworms, and only those from one class are usually used for vermicomposting. However, mostly foreign earthworms are used in the setup. Foreign earthworms are more expensive and harder to obtain than local earthworms. This makes the local farmers reluctant to try since they are expensive. The difference in vermicompost using two species of epigeic earthworms, a local earthworm and a foreign earthworm (Eisenia fetida), and normal compost without any earthworms was measured in this study. Both species of earthworms were placed in identical vermibeds consisting of partially composted goat manure and partially composted spent coconut flakes (SCF) with the ratio of 5:1 respectively in terms of weight. The vermibed moisture content was maintained at 60 – 70% throughout the whole process. The end products showed a difference from one another. The E. fetida showed a better result compared to the local earthworms in terms of the nutrient content presence and the adaptability of the earthworms during the whole process. However, the end product from the local earthworms was still better compared to the normal compost without any earthworms.
